How do I clip an object via texture?

[hell-raiser]

Gee, now I really learn to appreciate Electric Image...there materials had an additional channel for clipping maps, wich are like transparency-maps, but prevent any speculars or other effects in the clipped areas. Great for painting holes into stuff.

Is there any way to achieve this in XSI ??? Or do I have to paint my holes black in the specular-map ?

When you are connecting a transparency map to your material, connect it to the specular at the same time.
